I'm also getting ready to step up to a bull bar versus factory bumper. The only concern I have is the added weight to the front of the vehicle. How much heavier is it than say the weight of the factory bumper? As it is right now my 33's don't rub. I'm using a 3" spacer lift. I assume adding the additional weight of the bull bar might introduce rub? Does anyone have any input here? I have been looking at both the TJM T15 and the ARB. I ideally want to go with the lighter of the two. Any insight you can give on this would be appreciated.
